Response Verification Test of E-Defense Shaking Table using Test Bed Structure
(Jul. 2005) (
Test Number: E200501 )
Prior to the fully operational use of E-Defense, verification tests were conducted to confirm the response and performance of the shaking table and the measurement system when the full-scale test specimen was mounted on it. A five-story steel frame building 12 m wide, 9 m deep, and 20 m high was constructed as the test specimen, and seismic motions observed during the 1995 Southern Hyogo Prefecture Earthquake were input. As a result, it was found that the response of the shake table is affected by the resonance of the specimen, but this effect can be reduced by adjusting the input seismic motion.

Verification Experiment of Seismic Performance and Damping Effect of 2-story Steel Frame House
(Jun. 2006) (
Test Number: E200601 )
【Facility Rental Experiment Conducted by Daiwa House Industry Co., Ltd.】
In recent years, housing has been required to have seismic performance capable of withstanding earthquakes of the same intensity as the 1995 Southern Hyogo Prefecture Earthquake without collapsing. While this performance far exceeds design standards, if non-structural components can contribute to seismic performance, the load on the building structure can be reduced, making it possible to achieve the above performance. On the other hand, if the rigidity of the building increases significantly due to non-structural components, localized large stresses may act on the structure, potentially leading to a decrease in the building's seismic performance. To verify the above, experiments were conducted on each component, and based on the results, modeling and response analysis were performed. However, it is currently challenging to appropriately evaluate the combined effects of components and scale effects. Therefore, to understand the stiffness and damping of residential buildings and to develop numerical models, shake table tests were conducted on actual buildings using E-Defense.

(Feb. 2007) (
Test Number: E200606 )
As a part of “Special Project for Earthquake Disaster Mitigation in Urban Areas” supported by the Ministry of Education, Culture, Sports, Science and Technology (MEXT), an experiment of full-scale wooden houses built by traditional timber framework method was conducted. The method of the test structures were used to be common before 1950, in which the Japanese Building Standard Law was enacted, and those structures have aseismic elements whose behavior of performance at seismic events were not yet clarified. We focused attention on difference of foundation style, floor stiffness and roof style, and conducted experiments on eccentricity ratio, floor stiffness, roof style and column base style as parameters to validate their impact to aseismic capacity of houses.

Shaking Table Test of Full-Scale Conventional Wooden Frame House
(Feb. 2007) (
Test Number: E200607 )
As a part of “Special Project for Earthquake Disaster Mitigation in Urban Areas” supported by the Ministry of Education, Culture, Sports, Science and Technology (MEXT), a collapse experiment of full-scale wooden houses was conducted. 2 test structures, house C and D whose framework were the same of house A and B tested in November 2005, were built newly. The test structures were constructed based on the previous building standards which were used until 1981 and whose seismic performance was insufficient.
The purpose of the experiment on House C was to investigate the effect of aging on the seismic capacity of wooden house. The purpose of the experiment on House D was to verify the effect of partial seismic reinforcement compared with House B which was considered to be fully reinforced, specifically the lack of the reinforcement at joints.

Preliminary Experiment for Plane Frame Specimen with Testbed Loading Device
(Jul. 2007) (
Test Number: E200701 )
By using E-Defense shaking table, it is possible to excite full-scale large test specimens. However, experiments using such large test specimens cost considerably expensive, so depending on the purpose of the experiment, it may be more economical to test a key portion of a structure, such as a building's plan frame, to obtain the necessary data. Therefore, preliminary experiments were conducted to verify a method of loading a plane frame using a so-called “test bed” equipped with a multi-purpose inertial mass system. The test bed consists of a steel truss box with dimensions of 6m × 4.5m and a height of 2.7m, incorporating a concrete slab with dimensions of 3000mm × 4000mm and a mass of 30 tons. The plan frame of the test specimen was sandwiched between two test beds, and by connecting the test frame to the test beds, the horizontal inertial forces of the test bed during an earthquake were transmitted to the test frame. The detailed data and video obtained from this experiment are available.

Shaking Table Test of Small-diameter Piping-support System
(Aug. 2007) (
Test Number: E200702 )
【Facility Rental Experiment Conducted by Mitsubishi Heavy Industries, Ltd.】
Nuclear power plants in Japan are designed to satisfy seismic design requirements based on the “Regulatory Guide for Reviewing Seismic Design of Nuclear. Power Reactor Facilities.” Following the revision of the guideline in September 2006, the government requested operating companies to conduct seismic backchecks on existing plants. While seismic margin has been confirmed for important facilities at nuclear power plants through various seismic tests, seismic margin tests simulating simultaneous elastic-plastic behavior of piping and supports have not been extensively conducted to date. Based on the above, experiments were conducted using E-Defense to confirm the seismic safety of the entire piping-support system. Using 4-inch and 2-inch diameter pipes and pipe supports commonly found in nuclear power plants as test specimens, simulated earthquake motions equivalent to a major earthquake were input, enabling confirmation of the seismic safety of the small-diameter piping system, including pipe supports.

Experiments on Seismic Performance of 2-story Wooden Houses
(Jan. 2008) (
Test Number: E200706 )
【Facility Rental Experiment Conducted by Tama Home Co., Ltd】
In recent years, seismic performance has come to be one of the key considerations when purchasing a home. To minimize casualties and property damage caused by earthquakes, it is essential for home builders to continue constructing and supplying homes with high seismic performance. With this in mind, the E-Defense experiment was conducted to demonstrate that homes can withstand major earthquakes anticipated in the future without collapsing. As a test specimen, a two-story wooden frame house was constructed using a standard detached house with a floor plan of 8 m × 10 m, a first-floor area of 80 m2, and a second-floor area of 72 m2.
Initially, the structure with seismic grade 3 or higher was subjected to seismic shaking, followed by the removal of some diagonal bracing to simulate seismic grade 2 conditions, after which shaking tests were conducted. The results of the experiments indicated that non-structural components may significantly influence the overall structural performance of the house, among other findings.

Experimental Study on the Safety and Functionality of Indoor Spaces in High-rise Buildings during Large-amplitude Motion
(Jan. 2008) (
Test Number: E200707 )
A large-amplitude floor response of a high-rise building was reproduced by using 5-story steel frame test structure with two amplifying layers comprised of rubber bearings and concrete slab.
Realistic conditions of residential room as well as office room were reproduced and a tuned synthetic ground motion was input to the shaking table. The large-amplitude floor response corresponding to the maximum displacement of 1.5 m was reproduced in the test structure of 5-story frame. The response of the test structure was tuned to represent the floor response of the 30th floor of a 30-story high-rise building which was subjected to synthetic ground motion for Nagoya from a scenario Tokai-Tonankai earthquake. Dangerous phenomena in the office room, residential room, kitchen and living room were clarified and the resistant measure prepared in the same type of rooms showed significant improvement in terms of safety.

Study on the Response Characteristics of Horizontal Seismically Isolated Plants to Inputs Exceeding Design Motions
(Feb. 2008) (
Test Number: E200708 )
【Facility Rental Experiment Conducted by Central Research Institute of Electric Power Industry】
To understand the seismic behavior of the isolation system in ground motions exceeding the design seismic motion level and design motions, shake table tests of a horizontally isolated system were conducted using E-Defense at a scale closer to that of the actual structure. A test specimen consisting of an upper building model composed of an upper foundation plate and wall structure, and an isolation layer containing Lead Rubber Bearings (LRB), was constructed. Temporary design seismic motions and observed seismic motions from past earthquakes were input into the test specimen. The experimental results showed that, under design seismic motion levels, the horizontal acceleration response was reduced, while the vertical response exhibited amplification, among other phenomena.

Shaking Table Test for Verification of Seismic Performance of Cranes in Nuclear Facilities
(Oct. & Nov. 2008) (
Test Number: E200803 )
【Facility Rental Experiment Conducted by Hitachi-GE Nuclear Energy, Ltd.】
In the event of an earthquake causing damaged or fallen cranes at nuclear facilities, there is a possibility that safety-critical equipment such as spent fuel storage facilities may be damaged. In such cases, cranes must be equipped with fall prevention functions. Cranes are located at the upper part of buildings and are prone to response amplification. Based on the above, E-Defense experiments were conducted with the aim of understanding earthquake-induced nonlinear responses, especially in vertical motion, including load-bearing capacity, sliding/floating/collision, and verifying the performance of fall prevention functions. Based on a detailed investigation of the crane's structural overview and dynamic characteristics, the ceiling crane of a BWR reactor building was selected as the test specimen. The detailed specifications of the test specimen were determined by incorporating the shake table specifications of E-Defense. Due to constraints on the size of the shake table, the test specimen scale was set to 1/2.5. Simulated earthquake motions and observed motions from the 2007 Niigata Chuetsu-Oki Earthquake were input into the test specimen, and important data was successfully collected.

Test Number: E200804 )
NIED and Japan Housing and Wood Technology Center had conducted shaking table experiments on creation of design method and performance validation project of Traditional Wooden Houses under the support of Ministry of Land, Infrastructure, Transport and Tourism. There were two test specimens (House A and B) in this experiment. They were two 2-story wood-framed houses built in a traditional manner. The modules and floor area and height of each story were not the same for both specimens but the floor plans were almost the same. In the experiment, by inputting a ground motion such as observed ground motion of the 1995 Southern Hyogo Prefecture Earthquake, damage and behavior of the specimens under strong earthquake were confirmed.

Experiment to Evaluate Maintenance of Functions of Important Facility, Medical Facility
(Dec. 2008 & Jan. 2009) (
Test Number: E200805 )
Shaking table experiments had been conducted to evaluate ability of functional maintenance of medical facilities under earthquake disaster. A full-scale 4-story reinforced concrete building specimen simulating a hospital which contained a stuff station, a dialysis room, an operating room and a patient’s room each furnished with real medical equipment and furniture was set up to reproduce function of the medical facility more faithfully. Two hospitals of different kind of structure each, one for a base-fixed structure and the other for a seismic isolated structure, were compared and evaluated their functional maintenance by shaking table experiments. Comparative video of the experiments shows risk of the aseismic hospital and ability of functional maintenance of the seismic isolated hospital under a near fault earthquake ground motion. But even a seismic isolated structure which widely reduces damages against earthquake in general can be exposed to risk by long-period, long-duration earthquake ground motion such as synthetic ground motion for Sannomaru area, Nagoya from a scenario Tokai-Tonankai earthquake if one fails to take earthquake countermeasures.

Experimental study on Securing Indoor Safety in High-rise Buildings during Large Earthquakes
(Feb. 2009) (
Test Number: E200806 )
Since the 1995 Southern Hyogo Prefecture Earthquake, significant casualties have been caused by the overturning of furniture and fixtures during major earthquakes. Therefore, it is extremely important to ensure not only the seismic performance of buildings but also the safety of the rooms inside. In particular, in the upper floors of super-high-rise buildings, the shaking that propagates and amplifies through the building can continue for an extended period, potentially increasing the risk of damage inside the rooms. Based on the above, in collaboration with Hyogo Prefecture, E-Defense experiments were conducted to evaluate indoor safety in high-rise buildings. Furniture and office equipment were installed inside a test specimen with extremely high rigidity, designed for verifying the performance of the E-Defense shake table, to replicate residence spaces and offices. Additionally, to reproduce the large, slow-moving motions of high-rise buildings, amplifiers consisting of two layers of seismic isolation devices were installed beneath the test specimen. By inputting seismic motions observed during the 1995 Southern Hyogo Prefecture Earthquake and those assumed for the Nankai Trough Earthquake into a numerical analysis model of a super-high-rise building, the response motion of the upper floors was calculated and input into the test specimen. Useful image data on the damage conditions inside the building, as well as the effectiveness of overturning prevention measures, has been obtained.
